Purpose: The goal of paper is investigations of temperature distribution which is appearance during fabrication process of metallic glasses. In present work particular attention focused on system for registration of temperature distribution. Design/methodology/approach: Bulk metallic glasses in the composition as the following: Fe36Co36B19.2Si4.8Nb4 were fabricated by the die casting method. Distribution of temperature was carried out by a prototype measure system. Investigations were realized for casting process of the samples in form of rods with diameter 2, 3 and 4 mm. Temperature distributions were executed for series of samples. Moreover, investigations also enclosed structure characterization tested by X-ray diffraction and SEM. Findings: On the base of temperature distribution curves it can be observed that during casting of metallic glasses a temperature gradient have been occur. It should be note that prototype system allows to measure temperature only in cooper mould not inside of sample. Diffraction patterns confirmed that structure of tested samples was amorphous. Electron microscope observations revealed fracture morphology which is characteristic fore glassy structure. Practical implications: Analysis of temperature during casting process plays an important role in effective fabrication of metallic glasses. Cooling rate can be estimated on the base of results these analyse. Knowing the cooling rate, it could be possible to determine the glass forming ability of studied alloy. Originality/value: Investigations which have been taken in present work are novelty for the sake of optimization of casting process not only for metallic glasses, but also for nanocrystalline engineering materials.
